Sorry, confused again! I'm multitasking. :-) I'll get it straight
soon. Your local machine is a PPC mac, the remote is Intel mac. I
can test that at home. But that's even weirder now. What's
happening is the clients on the Intel machine are calling the GLX
library on the Intel machine, which then talks GLX over the network
to the X server on the PPC, which then uses hardware to render the GL
calls that result. Your error (Bad Request) comes from the X server
and is interpreted and repeated by glxgears to you. So something the
client GLX libraries said is making the PPC server unhappy.
I guess a good test would be what if the glxgears ran on Intel Mac
and the X server (localhost) was a linux box? That's one I'll have
trouble testing, but would be a natural next test.

Correct me if I'm wrong, but the X server in this case is running
on the local machine - PPC notebook - right ? Isn't it the client X
appllication that is running on the Intel mac ?

Oh, when the REMOTE machine is intel... hmm, I'll look and see if
I can reproduce. I'm sorry I misunderstood. I don't know why the
Intel X server would not be able to use GLX, though, that strikes
me as very strange bug.

I am able to see glxgears as well when the remote machine is
linux. It doesn't work when the remote machine is an Intel iMac.
Yes, I'm sure I'm using -Y. My local machine is a Powerbook G4.

it's something you're doing. Are you SURE you're using -Y?

Hi,
I can't seem to run opengl apps remotely using apple's X11.
Here is my setup:
Local machine: Powerbook G4 OS X 10.4
Remote machine: Intel iMac OS X 10.4
I'm using ssh -Y to log in remotely. glxgears and glxinfo
fails with the following message:
name of display: localhost:10.0
X Error of failed request: BadRequest (invalid request code
or no such operation)
Major opcode of failed request: 129 (Apple-DRI)
Minor opcode of failed request: 1 ()
Serial number of failed request: 13
Current serial number in output stream: 13
Other X apps like xterm, xclock etc. work fine.
Interestingly, with the same setup, if the remote machine is a
linux machine opengl apps work fine. I'm connecting through a
VPN - first I thought that could be the problem but since it
works with remote linux machines that couldn't be.
It will work even with a remote OSX machine if it's a PPC. This
looks like an OSX/Intel bug.
Any ideas would be appreciated.
